目的 探讨多层面螺旋CT仿真内窥镜与三维成像技术在胃肿瘤诊断中的应用价值。方法 对 2 2例怀疑胃肿瘤的患者进行多层面螺旋CT扫描后进行CTVG和三维成像 ,并与纤维胃镜结果对照 ,对发现异常的患者进行病理检查。结果 2 2例患者均成功检查 ,并通过胃镜或手术进行病理证实。从发现部位和病灶形态来看 ,本组病例以胃窦部多发 (14例 ) ,以溃疡型居多 (16例 )。对于病灶的检出 ,CTVG与FG均有 1例误诊。结论 多层面螺旋CT仿真内窥镜结合三维技术能达到与纤维胃镜检查同样的敏感度和特异性。
Objective To investigate the value of multi-slice spiral CT virtual endoscopy and three-dimensional imaging in the diagnosis of gastric tumors. Methods Twenty-two patients with suspected gastric tumors underwent multi-slice spiral CT scan and CTVG and three-dimensional imaging. Compared with the results of fiber gastroscopy, the patients with abnormal gastric cancer were examined by pathology. Results Twenty-two patients were successfully examined and pathologically confirmed by endoscopy or surgery. From the site of discovery and lesion morphology, this group of patients with multiple gastric antrum (14 cases), mostly ulcers (16 cases). For the detection of lesions, CTVG and FG were misdiagnosed in 1 case. Conclusions Multi-slice spiral CT virtual endoscopy combined with three-dimensional technique can achieve the same sensitivity and specificity as fiber gastroscopy.
